You call Saskatchewan's use of it a big scale issue?
My understanding is that was only temporary for that ruling. I hadn't even heard of it until recently. The big one was the Quebec use of it in the 1990s.
What? That's silly. The federal government can disallow any act of a provincial parliament.
My understanding is that power hasn't been tested. I suspect that's partly why Trudeau didn't use it.
Quebec largely HAS made English illegal and the response from the Left was applause for them protecting their delightful ethnic cultural values and language.
No. That's your perception only.
